To all -fwi/om it 'may concern.

Be it known that l, Wimmer Sroiiiirc, s citizen vof the United States, residing at Providence. in the county of Frei/idonee and Stete of Rhode Yisland, lieve Vinvented new :ind useful linpi'ofeinonts in Shockulisorhers, of which the following is ii specification.

The present invention relates to means for absorbing the vibrations and shocks in vehicle springs to suoli an extent as not to ceuse annoyance to the rider and strain to tlie springs oit' the vehicle, which would tend to cause such springs to crack or otherwise become disabled.

rlhe invention provides a Shock absorber embodying an expansilole helical spring and supporting means therefor oi novel forma tion, one of such supports being secured to the axle and the otliei'being siiackled or otherwise attached to tlie vehicle spring, the parts being arranged to control the vibra-- tions or shocks not taken up quick enough by the main spring and thereby overcome the objectionable Jeetures `herein mentioned.

The invention also provides a device which supplements the ectioiiot the mein spring ofthe vehicle and also serves to neutralize ythe vibration and other shocks which are not ordinarily taken up by the main spring of the vehicle and Wliicli tend to add to tlie inconvenience of the rider.

'llie invention also further provides an appliance which while acting as e shock ab! sorber does not interfere with tlie maximum movements of the mein spring end which is of such construction es not to be materially afl'ected by sideinoveinent Which would' tend ordinarily to produce inelective'actioii and cause lateral strain and render the eicieiicy of the device comparatively shortdived.

The invention consists of the novel feetures, details of construction end combinet-,ion of parte, which hereinafter will be more particularly set'fortli, illustrated and claimed.

Tlie'de Yice comprises a bracket which is adapted to loe secured tothe axle, a rod adapted to he connected hy ineens of e slicclrle or otherwise to the vehicle spring and bracket, and an interposed expansible helical spring; The bracket comprises an arni 1 and oase 2, seid erin being adapted to be secured to Vthe axle oi the vehicle in any manner :is o v ineens of s threaded shank 3. rThe hose 2 is arranged to occupy an approxiinetely horizontal position and is termed with :i central opening in wliicli'is litted a bushing 4 which retains the spring,f seat, shell D.A rllie rod extends vertically and is provided at' its upper end with a voke G end sit-its lower end with an eye 7 which. extends transversely and receives a bi'isliinp,Vr 8.- A shell 9 is mounted upon the base 2 and is proylded at its lower end with an inturned flange 10 which is confined between the. base 2 and en outer tiange et. the upper end of the bushing e. The shell 9 receives the lower portion of an expansible, helical spring 1l which is supported upon the base of tlie briicltet. The spring 1l rests upon the inturned flange l0 and is prevented from lateral .fiioveinent by ineens of the shell 9, The :volte is secured to the upper end of the rod 5 in any manner and rests upon the spring il and is retained in position thereon against lateral displacement by means of a raised portion l2 which enters a spring 11. As shown the upper end of the rod 5 is'threaded sind passes through an opening. of the yoke 6 and receives e nut 13. A housing 14 consisting ot e sliellincloses the springend shell 9 and extends over the volte 6 and serves to exclude foreign matte from the spring and to prevent the escape of' any lubricant applied to suoli spring and the shell 9. The housing M- inoves with the yoke gives l .e 6 and rod e. end is strengthened :it its lower g ananas thelnks 21 ahorizontal arrangement., l

pin22 connectsv .the links 20 `and 2l and the" rod 5. The bushing 8 mounted upon the pin 22 passes through the eye 7 of the rod 5 andthrough theopenings of the linjlisfll. The links 20 and 42l have a 'toggle arrangement and admit of the spring ll suppleinenting the action of the spring 19 asalso providing for the neutralizing of shock and vibration with the result that the occupant of the vehicle experiences comfortin riding and the vehicle is free from jar which ordinarily would add materially to the Wear of the parts,

From the foregoing description, taken in connectionvwith the Aaccompanying drawing, theadvantages ofthe construction and of the method of operation Will be readily apparent to those skilled in'the art to which.

theinvention appertains, and While I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and

that such changes may be made when desiredt as are Within the scope of the invention as claimed. v

Having thus described the invention, what is Claimed as new is l. In combination, a support embodying a base and an off standing portion, a yield able device mounted upon the said base, a connection suspended from the yieldable device andv passing therethrough and through the base, links embracing the support and the oi'standing portion thereof and pivotally connected at one end to such oil standing portion and at its opposite end to the be fore mentioned connection and other links connectin the vehicle spring with the rst mentione links and the said connection, said links having a toggle arrangement.

LA device of the character set forth, comprising a bracket embodying an arm, base, and olf standing portion, said base having an opening, a flanged bushing fitted in the opening of the base, a shell mounted upon the base and having an inturned lange which is coijned thereto by means of the flanged bushi g, an expansible helical spring mounted up, n the base, a rod passing through the spring and base and having an eye at its lower end, a. yoke connected tol the upper end o1@ said rod and mounted upon the spring, a housing inclosing the yoke,
